A sensor means is employed to sense a distance to the surface of a subject to be examined, so that a range image may be acquired. Intensity information may be acquired alongside the distance information. The distance information and intensity information may be evaluated to track the pose of the sensor means relative to the surface of the subject to be examined, so that anatomical data related to said subject may be displayed as seen from the position and/or orientation of the sensor means or display means. By moving the sensor means or display means along the surface of the subject to be examined, such as a patient in a hospital environment, the user hence gets the impression of being able to look directly into the human body.

Visualization of anatomical data by augmented reality

The invention relates to a method for navigation during medical interventions on tubular organ structures, characterized in that, before the intervention, static image data of the tubular organ structures are recorded and stored, the tubular organ structures are extracted from the image data and their course is converted into a geometric description used during the medical intervention for instrument/organ recording, and the instrument that is spatially localized by a tracking system is successively corrected in relation to the static data, by a transformation that is preferably defined by an optimization method, taking into account the geometric description and information on the previous distance covered by the instrument, or, conversely, the static data are successively corrected in relation to the instrument position, and thus the position of the instrument is associated with the anatomical structures in the static image data.

Incremental real-time recording of tracked instruments in tubular organ structures inside the human body

The invention relates to one or several navigation aids whose position can be used to maintain the recorded state of at least one partial structure of a non-bone structure. The navigation aid(s) is/are inserted into the non-bone structure.
